See that funny strip at the top of your Blogger blog that has your email and links at the right? What color is it? Look at the rest of your blog, and I'll bet some of you can change that so it matches the overall look of your design better.
You only get four choices - black, white, tan, or blue - but one of them is probably a better choice for your color scheme than any other. Go to Layout, click on that banner's edit link, and change for the better. It's a little thing, I know, but why not be the best you can be?
And don't forget to collapse your archive - that's on the same Layout page.
